Grüns Gummies: What’s In Them, Do They Work, and Are They Safe?

Answer:

Grüns Superfoods Greens Gummies are, essentially, gummy vitamins with added fiber, as well as powdered fruits and vegetables (the "greens") that we consider window dressing and not the main source of the fiber or other nutrients.

Based on the listed ingredients, a pack of Grüns (8 gummies) appears to be generally safe for an adult or older child to take. However, they are expensive ($2.39 per pack) compared to high-quality multivitamins that can cost as little as 5 to 15 cents per day. With Grüns, you’re paying a lot extra for a few grams of fiber that you could be better off getting from whole foods that provide more minerals, particularly magnesium and calcium – which are not in Grüns.

What’s in Grüns?

Fiber

Grüns lists 6 grams of fiber (about as much as in 1 ½ medium-sized apples) per 8-gummy pack. The fiber seems to come mostly from tapioca fiber, inulin root powder, and pectin.

A lawsuit filed in July 2026 against Grüns claims that tests showed it to contain somewhat less fiber than claimed on its label (5.27 grams vs 6 grams) and somewhat less niacin (14.6 mg vs 16 mg).

Sugar

The "low-sugar" version of Grüns contains 8 grams of added sugar (about 2 teaspoons of sugar) per pack, so 1 gram per gummy. This is only slightly less than the amount of added fruit/veggie powder (8.7 grams). The sugar-free version has no added sugar and is sweetened with allulose and Reb M from stevia.

Vitamins & Minerals

A pack of 8 gummies claims 100% of the Daily Value for vitamins A, C (103%), D, E, and of the B vitamins (thiamin, biotin, riboflavin, pantothenic acid, niacin, folate, B6 and B12). It also claims 25% of the Daily Value for iron, zinc, copper, manganese iodine, selenium, chromium, and molybdenum). These amounts are generally safe for adults and older children.

Be aware that, like most other gummy vitamins, Grüns provide no calcium or magnesium, which you will need to get these from your diet, from which you should also get more iron, zinc, iodine and other essential minerals.

Calories

The low-sugar version of Grüns lists 50 Calories per pack and the sugar-fee version lists 20 Calories -- likely from starches in the tapioca and fruit and vegetable powders listed in its "Core Nutrients Blend."

Do Grüns Work?

Grüns states that, in a survey of users, 67% reported "better, more regular digestion." However, a user survey is not the same as a clinical trial, and no published clinical study appears to show whether Grüns supports gut health as claimed. The 6 grams of fiber per pack may help some people with regularity.

The website indicates that a 12-week clinical study in 120 healthy adults aged 23-59 was performed and showed that taking Grüns increased folate 20.5% and vitamin C by 40.1% compared to placebo. However, many important details about how the study and how its data was analyzed have not been shared. The study has not been published in a peer-reviewed journal and Grüns has not yet responded to our request for additional information.

Are Grüns Safe to Take?

At 1 pack per day, the amounts of vitamins and minerals in Grüns should be generally safe. Even 2 packs per day would not exceed the tolerable upper intake levels for adults or older children.

The allulose in the sugar-free version could cause some gastrointestinal symptoms, like bloating from gas, as could the fiber in both versions.

Grüns reports on its website that its products are tested by a third party for heavy metals and that these tests have found no more than 0.5 mcg of arsenic, cadmium, lead, or mercury. If these values are per one-pack serving (8 gummies), the product would meet safety and warning limits. Unfortunately, Grüns does not indicate if the values are per pouch, pack, gummy, gram or other unit and are meaningless without that information. Grüns has not responded to our request for clarification.

Cost

Grüns are sold in a large pouch containing 28 individual packs. Each pack (which is one serving), contains 8 gummies. The large pouch sells for $67 on Amazon (sold by Grüns), which works out to $2.39 per pack (30 cents per gummy), which makes Grüns a very expensive multivitamin compared to high-quality multivitamins that can cost as little as 5 to 15 cents per day.

Bottom line

Grüns may be a convenient gummy multivitamin with added fiber, but it is expensive, lacks calcium and magnesium, and has limited published clinical evidence for its broader health claims. People who want fiber and minerals are likely better served by whole foods, along with a lower-cost multivitamin if one is needed.
